Re: calendar_decode2.ncl function question

Ioana,

The first time value you printed out was 25550. Since this is supposed to be "days since 1870",
then if you take this number and divide it by 365, you get 70 (years). Your start date is 1870,
and 70 years after this is 1940.

It looks correct to me.

You may want to double-check your input time values.
